Product Overview

The rear transmission mount, OEM number A2122400418, is fitted across an exceptionally wide range of Mercedes-Benz platforms, including the C-Class (W202, W203, W204), E-Class (W210, W211, W212, C207), CLK-Class (C209), SL-Class (R230), SLK-Class (R170), CL-Class, and S-Class (W140, W220), spanning production from the 1990s through the 2010s. Since this single mount covers such a broad cross-section of Mercedes-Benz's rear-wheel-drive lineup across multiple generations, it's an exceptionally high-turnover part number worth stocking in significant volume for distributors serving Mercedes-Benz drivetrain parts demand.

A worn or failing transmission mount typically shows up as excessive vibration felt in the cabin, a clunking noise during acceleration or gear shifts, or visible cracking in the mount's rubber body. GSK Auto manufactures this mount to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Transmission Mount?

Function: The transmission mount secures the transmission to the vehicle's chassis while absorbing vibration and movement generated during gear changes and engine operation.

Working Principle: A rubber element inside the mount cushions the connection between the transmission and chassis, isolating vibration and shock from reaching the cabin while still holding the assembly firmly in place.

Importance: On a rear-wheel-drive platform, a properly functioning transmission mount is essential for smooth, quiet ride quality and preventing excess drivetrain movement.

Common Failures & Signs: Excessive vibration felt through the cabin, especially at idle. Clunking or knocking noise during acceleration or gear shifts. Visible cracking, tearing, or sagging in the mount's rubber body. Increased drivetrain movement noticeable when accelerating or braking.
